I/P-frame delta QP
This parameter sets the ratio of the I-frame quantization (QP) to the P-frame quantization
(QP). For example, you can set a lower value for I-frames by moving the slide control to a
negative value. Thus, the quality of the I-frames relative to the P-frames is improved. The total
data load will increase, but only by the portion of I-frames. The basic setting Auto
automatically adjusts to the optimum combination of movement and image definition (focus).
To obtain the highest quality at the lowest bandwidth, even in the case of increased
movement in the picture, configure the quality settings as follows:
1.
Observe the coverage area during normal movement in the preview images.
2. Set the value for Min. P-frame QP to the highest value at which the image quality still
meets your needs.
3. Set the value for I/P-frame delta QP to the lowest possible value. This is how to save
bandwidth and memory in normal scenes. The image quality is retained even in the case
of increased movement since the bandwidth is then filled up to the value that is entered
under
Maximum bit rate .
Background delta QP
Select the appropriate encoding quality level for a background region defined in Encoder
Regions. The lower the QP value, the higher the encoding quality.
Object delta QP
Select the appropriate encoding quality level for an object region defined in Encoder Regions.
The lower the QP value, the higher the encoding quality.
Default
Click Default to return the profile to the factory default values.
5.4 Encoder Streams
Note: If you access this menu while the camera is recording, the following message appears at
the top of the page:
Recording is currently active. Therefore, for ‘Current profile’ the respective stream profile
selected for recording is displayed for information.
Stream prioritization
Select the stream that should not drop any frame.
For each stream, select the appropriate options in the fields that follow.
Coding standard
Select the coding standard (H.264 or H.265) for the stream.
VCA overlays
Select the video stream into which to embed VCA overlays.
Non-recording profile
Select one of the following profiles for each stream:
Profile number Default Profile name Description
Profile 1 HD Image Optimized For an HD image, the video bit rate and frame
quality are adjusted to ensure that the picture
quality is the priority.
Profile 2 HD Balanced For an HD image, the video bit rate and frame
quality are adjusted to a median profile for
everyday use.
